The sun is behind earth at that time. The earth's shadow makes the eclipse. Some areas of the world will see a full eclipse and other's will see a partial.
A Lunar eclipse occurs only when the moon is in its full moon phase.
As far as I know, there are full and partial eclipses of the full moon and every other moon phase. It all depends on position and timing of the moon and the planet or star that eclipses it. Full or partial eclpise can only occur at Full Moon.
This is a lunar eclipse, not an eclipse of the Sun. In this case the answer is the Full Moon.
